I'm not a developer, but have you tries xfs_repair -n ? As you crashed,
probably the xfs log is damaged, needing a "xfs_repair -L", but wait for
a more competent answer before you do this.

Oops, I already did "xfs_repair -L", successed. It's in production
environment, didn't have too much time to figure out why :-(

That was probably the only chance anyway.
I'm wondering about the crash. Even if the log is full of shit because
of a crash, xfs should not drive to hell but better report the fact and
exit. But maybe such strict checking is not worth the effort, as every
competent admin does xfs_repair then anyway?

It looks like you hit one of the XFS_WANT_CORRUPTED_GOTO checks in
xfs_error_report, and we hit something in there that isn't initialized
that early during the mount process. My guess it's actually the
mp->m_fsname dereference in xfs_fs_vcmn_err. It's fixed by the message
rework in 2.6.39+, but that will only prevent the crash, you'll still
get an error and the log recovery will be aborted. If you can get a
more recent kernel on the box I'd be curious what the output form it is.
Did you run older kernels on this machine before? Before 2.6.33 device
mapper support for barriers (aka cache flushes) was incomplete and
frequently led to free space corruption if people left the volatile
write caches on. For MD underneath it event took a bit longer.
If you just want to continue using the filesystem you can nuke the
log using xfs_repair -L.
